公路隧道入口彩色路面设计现状与分析

Review and Analysis of Colored Pavement Design at Entrance of Highway Tunnel

摘要:

公路隧道入口处彩色路面的合理铺设对提高视觉警示、保证驾驶安全有重要意义。从公路隧道入口处的交通特性出发，通过大量调研总结了目前隧道入口常见的彩色路面铺设型式，根据速度过渡需求，考虑驾驶知觉?行为模型、透视原理和闪现率原理给出了彩色路面铺设位置、长度以及条纹间距等参数的设计建议，并从亮度过渡角度提出了增大安全距离和设计方案理论验证两种考量方式。最后，从隧道入口处彩色路面的铺设需求出发，讨论了当前隧道入口彩色路面设计面临的主要问题，以期为彩色路面的设计与进一步的研究提供参考。

Abstract:

The reasonable laying of colored pavement at the entrance of highway tunnel is significantly important for improving visual warning and ensuring driving safety. Based on the traffic characteristics at the entrance of the highway tunnel， the current common laying types of colored pavement at the entrance of the tunnel are summarized after a large number of investigations. According to the requirements of speed transition， and based on the model of driving perception-behavior， perspective principle， and the flash rate principle， the design suggestions of colored pavement laying position， length， and stripe spacing are given. From the perspective of brightness transition， two methods of increasing safety distance and theoretical verification of design scheme are proposed. Finally， starting from the laying requirements of the color pavement at the entrance of the tunnel， the main problems faced by the current colored pavement design at the entrance of the tunnel are discussed in order to provide reference for the design and further research of colored pavement scheme.
